Specification ofLetters Patent.

Patented .Tune 8, 1909.

Application filed April 16,21908. Serial No. 427,471.

To all whom it may concern:

Be it known that I, FRANK HosroRD, citizen of the United States,residing at Sterrett, in the county of Ellis and State of Texas,

have invented certain new and useful Improvement are, the simplificationof the rais-y ing, lowering and swinging means.

Finally the object of the invention is to provide a device'of thecharacter described that will be strong, durable, eiiicient and simple,and comparatively inexpensive to construct, also one in which theseveral parts will not be liable to get out ofworking order.

With the above and other objects in view, my invention has relation tocertainnovel features of construction and operation, an example of whichis described inthe following specification and illustrated in theaccompanying drawings, wherein:

Figure 1 is a side elevation of the improved'harrow, Fig. 2 is a planview, Fig. 3 is a front elevation, and Fig. 4 is a longitudinal sectiontherethrough.

In the drawings, the numeral'ly designates a transverse axle-shaft whichis supported to turn in a bearing bracket 2 vsecured to the under sideof a central tongue 3 which suitably supports a drivers seat 4. lTheaxle is bracedl by forwardly converging braces 5 having suitableconnection with the axle and the tongue.

Ground wheels 6 are mounted on suitable hub-sleeves arranged to slidelongitudinally on the axle 1 at .each end thereof and transversely ofthe harrow. These sleeves have rotatable connection with hook collars 8which in turn have pivotal connection with the ends of rods 9 extendingto levers 10 pivotally connected to sectors 11 suitably fixed on theaxle at each side of the tongue. By swinging these levers, whichcarr'ymeans for locking them in place, the collars are in any desiredmanner.

l moved longitudinally on the axle which causes the wheels 6 to be movedin or out transversely of the harrow as will be apparent. Either wheelcan be moved and the harrow thus maintained in the proper position withrelation to the row and each wheel retained in its respective furrow.

Disposed longitudinally of the harrow and beneath the axle two pairs ofside bars 12 are arranged, the central bars which lie under the tonguebeing attached by flexible connections 13. Each pair of bars rigidlysupports transverse rodsv 14. The side bars are supported by straps 15extending upward toward the axle and secured to transverse hanger bars16, which in turn are connected to longitudinal flat springs 17 securedon opposite sides of a transverse supporting bar 18. This bar ispivotally supported on the end of a curved arm 19 projecting from acollar 20 loosely mounted on the shaft 1 and forming the bottom of avertical hand lever 21. This lever projects in juxta-position to thetongue 3 which carries a sector 22 adapted to be engaged by a plunger 23mounted on the lever 21 and by which the parts are locked in position.

V-shaped yokes 24 having their forward ends loosely bent about the rods14, carry at their apexes, a suitably secured block 25, in each of whicha spiked tooth 26 is fastened These yokes are positioned so as to standin staggered relation from front to rear of the harrow. It islobviousthat two gangs of teeth are carried, those supported on the rods 14between one pair of side bars 12 constituting one gang and thosesupported on the rods between the other pair of side bars constitutingthe other gang.

A frame 27 is supported over each gang by pivotally connected arms 28loosely mounted on each rod 14, the said arms tilting or incliningrearwardly and the yokes lying horizontally as shown in Fig. 4. Theseframes carry on their under sides suitably secured cups 29 each normallyhanging slightly in rear of one of the teeth 26 and a coiled spring 80extending from the cup to the upper end of the adjacent tooth andconnected thereto. These springs resiliently hold the teeth and yokes inposition and when placed under tension tend to force the teeth and yokesdownward.

A pair of longitudinal runners 31 extending below the rods 14 aresupported from each frame 27 by links 32 having pivotal connection withthe frame and the runners and extending forward and downward, said linksresting on the rods 14 as best shown in Fig. 4. It is obvious that therunners are held elevated by the engagement of the links with the rodand when the frames 27 are moved forward the links will force therunners downward on the accumulated material and below the teeth 26.IVhen the frames are moved forward, they will swing on the arms 28 whichwill raise them and owing to the coiled spring connections, swing theteeth 26 and the yokes upward. The combined downward movement of therunners and upward movement of the teeth, serves to project the runnerswell below the ends of the teeth and free them from the accumulatedmaterial. This forward movement of the frames 27 is carried out by meansof rods 33, one attached to the central rear portion of each frame atits lower end and to an arm 34- at its upper end. Each arm 34 is rigidlysecured to the axle and projects upwardly at an angle therefrom. On theopposite side of the tongue from the lever 21, a lever 35 projectsupward and rearward from the axle l on which it is secured and carries alplunger 36 which engages a toothed sector 37 secured to the side of thetongue. By pushing this lever forward, and rocking the axle l, the arms34 are swung upward and the frames 9.7 swung forward which depresses therunners and raises the teeth as above described. It is obvious that thisoperation may be expeditiously carried out and the accumulated materialreadily discharged.

By reason of the fiat springs 17 it is obvious that each gang isresiliently supported as a unit so as to absorb any severe shock or jar.By pushing the lever 2l forward the gangs are raised, while by pullingthe said lever rearward the gangs are lowered. It is also to be observedthat the farther back the lever 35 is pulled, the lower the frames 27are swung and the tension or compression of the springs 30 and thedepression of the teeth 26 increased proportionately.

That I claim, is:

l. In a riding harrow, the combination with an axle and wheels movablymounted on the ends thereof, of a harrow frame resiliently hung from theaxle, runners disposed beneath the harrow frame, means for rocking theaxle, and means operated by the movement of the axle for shifting therunners vertically.

2. In a riding harrow, the combination with a wheel supported axle, of aharrow frame resiliently hung from the axle, runners disposed beneaththe harrow frame, means for rocking the axle, means operated by themovement of the axle for shifting the runners vertically, and means forbodily aising and lowering the harrow frame and the runners.

2%. In a riding harrow` the combination with a wheel axle, of a harrowframe, teeth movably connected to the frame, means for placing the teethunder spring tension, runners disposed beneath the frame and extendingthereunder` and means for simultaneously moving the teeth and runners inop` posite directions toward and from the axle.

4. In a riding harrow, an axle, ground wheels loosely mounted en theends of the axle, frames hung from the axle, a gang of movable harrowteeth carried by each frame, means arranged over the teeth adapted toswing the same when swung, and runners havingdirect connection with saidmeans so as to be shifted vertically thereby.
